SynchronizationOption Enumeration

Specifies the type of automatic synchronization requested by the component.

Namespace: System.EnterpriseServices
Assembly: System.EnterpriseServices (in system.enterpriseservices.dll)

[SerializableAttribute] 
public enum SynchronizationOption
/** @attribute SerializableAttribute() */ 
public enum SynchronizationOption
SerializableAttribute 
public enum SynchronizationOption
 Member nameDescription
DisabledCOM+ ignores the synchronization requirements of the component when determining context for the object. 
NotSupportedAn object with this value never participates in synchronization, regardless of the status of its caller. This setting is only available for components that are non-transactional and do not use just-in-time (JIT) activation. 
RequiredEnsures that all objects created from the component are synchronized. 
RequiresNewAn object with this value must participate in a new synchronization where COM+ manages contexts and apartments on behalf of all components involved in the call. 
SupportedAn object with this value participates in synchronization, if it exists. 

The following code example demonstrates the use of the SynchronizationOption type.

using System;
using System.EnterpriseServices;
using System.Reflection;

// References:
// System.EnterpriseServices

// An instance of this class will not join an activity, but can share its
// caller's context even if its caller is configured as NotSupported,
// Supported, Required, or RequiresNew.
[Synchronization(SynchronizationOption.Disabled)]
public class SynchronizationAttribute_SynchronizationDisabled :
    ServicedComponent
{
}

// An instance of this class will not join an activity, and will share its
// caller's context only if its caller is also configured as NotSupported.
[Synchronization(SynchronizationOption.NotSupported)]
public class SynchronizationAttribute_SynchronizationNotSupported :
    ServicedComponent
{
}

// An instance of this class will join its caller's activity if one exists.
[Synchronization(SynchronizationOption.Supported)]
public class SynchronizationAttribute_SynchronizationSupported :
    ServicedComponent
{
}

// An instance of this class will join its caller's activity if one exists.
// If not, a new activity will be created for it.
[Synchronization(SynchronizationOption.Required)]
public class SynchronizationAttribute_SynchronizationRequired :
    ServicedComponent
{
}

// A new activity will always be created for an instance of this class.
[Synchronization(SynchronizationOption.RequiresNew)]
public class SynchronizationAttribute_SynchronizationRequiresNew :
    ServicedComponent
{
}
